1. Enter I Butler and select "Mobile phone cleaning/space management".
2. Delete the cache garbage.
3. Restart the phone before installation.
4. If the signatures still conflict, please open the Settings page and select More Settings.
5. Select "Application".
6. Select "All" and find the name of the software to be installed on the page to be uninstalled.
Signature conflict is mainly due to the existing files or applications for installing software in the mobile phone, which makes the new installation software unable to overwrite the original installation software, usually because the storage space of the mobile phone is more than the files. Cleaning can avoid this conflict.
